If the swingarm is plain square box section, then it will be Mk1, if the swingarm looks like it's made from the same shape extrusion as the frame and has a torque arm from the rear caliper to the frame, it will be a Mk2.
Mk2 CDI has PGM-II moulded into the black plastic cover - easily identifiable.
